  • Closed circuit ball mill Basics revisited ScienceDirect

    Since the early days, there has been a general consensus within the industry and amongst grinding professionals that classification efficiency and circulating load both have a major effect on the efficiency of closed circuit ball mills. However, the effect of each is difficult to quantify in practice as these two parameters are usually interrelated.

    Closed Circuit Ball Mill In a series of open circuit tests reported by Dorr and Anable (1934) limestone was ground at various feed rates in a 3 ft ball mill. The production of fine material (final product) increased with larger feed rates, and the relationship is a straight line in log-log space. This represents the well known first order
